Abstract
The extracted Oryzanol under the optimum conditions were determined , Five temperatures were used which are 30, 40, 50, 60, and 70 degrees Celsius and the results showed that the ideal temperature for extraction is 40 Cº and Five heating times were used which are 10, 20, 30, 40, and 50 minutes and the results showed that the ideal heating time for extraction is 20 minutes . As for the volume of the solvent mixture used in the extraction, five sizes were used, which are 15, 35, 55, 75, and 95 ml, and it was found that the best volume for extraction is 95 ml in addition fife ratios of Solvent Hexane : Isopropanol were used for extraction 1:1 , 1:3 , 3:1 , 3.5:0.5 , 0.5:3.5 V/V and the ideal ratio for mixing the hexane solvents: isopropanol 1: 3 volume : volume.
